Turbulence: All Mixed Up

If you've ever ridden in an airplane, you might have some idea what turbulence
is. When an airplane flies through a turbulent place in the atmosphere it will
bounce around a bit as the wind outside blows the plane in different directions.

Turbulence is just a fluid
moving around crazily so it's all mixed up. Turbulent flows are filled with
swirling and spiraling motions. This is especially true if the object itself
is spinning like a planet or star where the
Coriolis effect causes winds and currents to curve and wiggle around. It's
difficult to predict what a turbulent flow is going to do because of something
called the butterfly
effect.
